file system, kernel or hardware raid failure?
...e block - inode=22561891, block=90243144.
I need to find the cause(s) of the problems. So far I have these
questions/concerns:
- Kernel bug? (This is Ubuntu 8.10 with 2.6.27-7-server)
- Filesystem bug/failure?
- Did the RAID controller fail to detect a failing drive? This is an
Adaptec aoc-usas-s4ir running on a Supermicro motherboard.
I suspect that one of the drives (RAID 6 btw) has failed, but I'm not
sure what to do from here.
Any ideas? Thanks in advance.

SAS or SATA HBA with write cache
Anyone know of a SATA and/or SAS HBA with battery backed write cache?
Seems like using a full-blown RAID controller and exporting each individual drive back to ZFS as a single LUN is a waste of power and $$$. Looking for any thoughts or ideas.
Thanks.
